In carrying out my present invention orimstable and StateofMassachu'setts,have made provement, I, by means of a punch, forni anew and useful invention, having reference holes in the plate, and pressupward above to the Manufacture of Sets of Artificial Teeth; the surfaceof the plate, and in the form of and I do hereby declare the same to befully hooks or .aples, the parts of the plate forced udescribed in thefollowing specification, and 4 from it in making the holes;

representedin the accompanying drawings. g In the drawings, A denotesthe suction- The nature of my invention consists of an plate, B B theblocks of teeth, and C the aluminium plate for supporting the'teeth byvulcanite composition, the-whole being arineans of a-vulcanizablecomposition of caouti ranged as represented. The plate has holes chonc,as made lwith hooks or projections: a a, Snc., punched through ,it, withthe parts punched up from it, and arranged in manner I b b b ofthe metalpartially separa-ted from the and with holes, as hereinafter described,such i plate in the process of forming such holes projection and holesbeing for the purpose of l raised above the surface of the plate, eitherholding the plate to the vulcan'ite.
